Interview Course Based on Story Questions

# Problem statement
This challenge is an extension of the previous challenge. Again, you will be given a non-empty string `s` and a list of strings called `subs`. The `subs` list contains a unique set of strings. This time, you have to find a list of all the strings that can be created by breaking down string `s` into space-separated sequences of one or more strings from the `subs` list. A single string from `subs` can be reused multiple times in the breakdown of `s`. 

## Input
The first input will be a non-empty string called `s`, and the second input will be a list string called `subs`. The following is an example input:
```python3
magically
["ag", "al", "icl", "mag", "magic", "ly", "lly"]
```
## Output
The output will be a list of strings that contain all the possible strings that can be formed by breaking the string `s` in a space-separated sequence of strings from `subs`. The following is an example output:
```python3
['magic lly', 'mag icl ly']
```
